  • Talking doll
    Patent number: 4805328
    Abstract: A means of animating the features of a doll or mannequin responsive to an audio signal. The invention utilizes an open loop electromechanical drive mechanism that is actuated by electronic drive signals derived from an audio signal. The electronic drive signals are of a simplified on-off characteristic based upon thresholding of the audio signal. When combined with the spring rate and drive ratio of the mechanism and the electrical characteristics of the motor, realistic animation of speech or other movements is created.
